Hello Tim,
Wow yes you could get some GREAT never attempted shots with racing drones! Various pan shots down the line at super speed would be awesome, plus some drone aerobatics thrown in - the footage would be incredible! One thing though ... some racing drones are really loud, much louder than phantom 4 etc ... i don't mind the noise of average drones over head but the racers can be too loud! So please make sure all the surfers and beach users are cool with your drone filming!

Good to meet you - I like your blog so am following you now also :D
